You've got it backwards. MPEG4 and H.264 play in standard QT 7, but
MPEG 1 and 2 are part of a $20 MPEG playback upgrade, that isn't
even part of Pro, AFAIK....

Hi Caleb,
Thank you for your input on this query. I was able to convert/
transcode the file into MPEG4 and then open it up in Quicktime and in
iMovie.
However, the quality is not great....lots of tiny blocks and a lot
of video/audio "stuttering" that was not present when I played the
original mpeg video file in VLC.
If I purchase this upgrade, would it allow me to import the original
video into iMovie without the loss of video quality that I described
above ? i.e. with the MPEG-2 Playback Component upgrade, will I be
able to open the original file directly into Quicktime or import into
iMovie and get close to the original quality of video (which was very
clean/sharp) ?
If so, I'll go ahead and buy it.
Amber
Amber, there is no guarantee that the MPEG-2 Component will playback
your relatives' videos. Is the video your relatives sent to you
indeed MPEG-2? It could very well be MPEG-1. As Caleb incorrectly
posted, MPEG-1 playback is and has been built-in to Quicktime for
many versions. The problem is either the files your relatives sent
were not mastered correctly, so Quicktime is not opening them, or
they are in a format Quicktime doesn't handle, like MPEG-2, or they
are not really MPEG at all and are just mislabeled as such (they may
be some Windows Media codec).
How long are the videos? If they are only a few minutes long and you
have lots of disk space to use temporarily, try to use ffmpegX or VLC
to transcode the video to DV. Or try H.264 instead, as I too have
seen the ffmpeg MPEG4 encoder to be buggy. Going the DV route will
produce a better end result, since you will only be transcoding once,
not twice.
If you are still having problems, can you drop the relatives MPEG
files onto the window in ffmpegX? In the status boxes on the left
side, it should tell you what format, resolution, bitrate, etc the
"Video" and "Audio" are. The GUI uses mplayer to read out this
info. What does it say about those files?
